Correlation of in situ 5-HT and CGRP release from the same dural or trigeminal ganglion samples. A Correlations of constitutive release (all baseline measurements) from the dura, soma-poor and soma rich TG. A significant negative correlation was observed. B Correlations of constitutive release from the soma-rich TG only, and here a significant negative correlation was observed. C The stimulated release (addition of 60 mM KCl (K⁺) or (D) 100 nM capsaicin, of 5-HT and CGRP from the same soma-rich TGs. Significant positive correlation was observed for K⁺ which contrasts to negative correlation observed with capsaicin. Data are shown as individual data points with p values and R² obtained from the correlation analysis
